[SOLVED] P0C87 Code: Hybrid Battery Temperature Sensor ‘g’/’h’ Correlation – How To Fix

The automobile fault code P0C87 indicates a problem with the hybrid battery thermistor.

This can cause the engine light to turn on or the service engine soon warning light to illuminate.

The possible causes include a faulty hybrid battery thermistor, a faulty battery smart unit, an open or shorted hybrid battery thermistor harness, or a poor electrical connection in the hybrid battery thermistor circuit. To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion.

Additionally, look for any broken, bent, pushed out, or corroded connector pins.

The repair time for this issue is estimated to be around 1.0 hour. It is important to address this problem promptly to prevent further damage to the hybrid battery system.

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p0c87 fault code.

  • The symptoms of the automobile fault code p0c87 include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The fault code p0c87 can be caused by a faulty hybrid battery thermistor, battery smart unit, open or shorted harness, or poor electrical connection.

  • The fault code P0C87 can be caused by: a faulty hybrid battery thermistor, a faulty battery smart unit, an open or shorted hybrid battery thermistor harness, and a poor electrical connection in the hybrid battery thermistor circuit.

To fix the automobile fault code p0c87, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p0c87, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the issue.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
  • This fix is estimated to take approximately 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p0c87 are the estimated repair time of 1.0 hour and the typical hourly rate charged by auto repair shops, which ranges from $75 to $150.

The P0C87 fault code refers to a correlation issue between the hybrid battery temperature sensors ‘G’ and ‘H’. These sensors are located in three different areas of the HV (high-voltage) battery in the vehicle.

Each sensor contains a thermistor that measures the resistance, which changes with the HV battery temperature. When the battery temperature is low, the thermistor resistance is high, and vice versa. The battery smart unit utilizes these temperature sensors to detect the HV battery temperature and sends the information to the power management control ECU.

Based on this data, the power management control ECU regulates the blower fan.

The blower fan is activated when the HV battery temperature exceeds a predetermined level. The P0C87 fault code indicates that there is a problem with the correlation between the ‘G’ and ‘H’ temperature sensors. This issue may affect the accuracy of the HV battery temperature readings and the control of the blower fan.

What are the possible causes of the automobile fault code p0c87?

If you see the engine light or service engine soon warning light on, the fault code P0C87 could be the culprit. This code is often caused by a faulty hybrid battery thermistor, a faulty battery smart unit, an open or shorted hybrid battery thermistor harness, or a poor electrical connection in the hybrid battery thermistor circuit. To fix this issue, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Also, look out for broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the wiring harness and connectors to fix the fault code p0c87?

If you’re dealing with the fault code p0c87 and your engine light is on, it’s time to take a closer look at the wiring harness and connectors. The possible causes include a faulty hybrid battery thermistor, a faulty battery smart unit, an open or shorted hybrid battery thermistor harness, or a poor electrical connection in the hybrid battery thermistor circuit. To fix the issue, visually inspect the wiring harness and connectors for any signs of damage. Check for broken, bent, pushed out, or corroded pins on the connectors. Don’t forget to examine the components as well.

What should I look for when checking for damaged components and connector’s pins to resolve the fault code p0c87?

To resolve the fault code p0c87, start by checking for damaged components and connector’s pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any signs of damage such as broken, bent, pushed out, or corroded pins. By doing this, you can identify any issues with the hybrid battery thermistor or the battery smart unit. Make sure to also check for any open or shorted circuits or poor electrical connections. Taking these steps will help you pinpoint the cause of the problem and guide you towards the necessary fix.
